"I think it is worth knowing why it will never work and consequently why we should not be wasting our time, energy, brain power and money in researching it."
Grrr and the flat earth people warned the sailors not to sail too far out to sea or they might sail off the edge. There is some good information on hydrogen and fuel cells at Knowledge Publications.com That is if you don't mind wasting your time.

Araoa's post made me look more into H2 than I already have and in doing so, whilst specifically trying to discover the energy used in compressing H2 to the standard 350 and 700 BAR pressures used (700BAR = 10,000psi), I came upon an interesting document that I would encourage anyone with an interest in EVs to read... http://publications.jrc.ec.europa.eu/repository/bitstream/111111111/6013/1/EUR%2020995%20EN.pdf Unfortunately it is rather dry but if there was sufficient interest I would be willing to précis it - tho I can't promise to be very unbiased.
